Tetraphenylcyclopentadienone is a dark purple to black crystalline solid at standard temperature and pressure. Because of its highly conjugated nature this organic compound can be analyzed in the UV spectrum. Tetraphenylcyclopentadienone has a propeller shape in its 3D conformation. The four phenyl rings are rotated out of the plane compared to the central ring because of steric repulsion with each other.
